Patent JP-H1182184-A (JP)
Title: Internal combustion engine system
Inventor: TAKAHASHI NOBUHIRO
IPC: F02B37/00
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To use a compact supercharger in comparison with the exhaust quantity of an engine by lengthening the flowing time of exhaust gas in an EGR passage until cooling water temperature reaches a set temperature, thereby enhancing heating effect and regulating exhaust pressure. SOLUTION: An EGR passage 10 connecting an exhaust manifold 4 to an intake manifold 3 is piped in such a way as to be inserted through the inside of a water jacket 2a of an engine 2, and cooling water is heated by the heat of exhaust gas flowing in the EGR passage 10 to enhance heating effect. When water temperature detected by a water temperature sensor 21 is in a range of the set water temperature or lower, an ECU 20 opens an auxiliary valve 13 when an EGR valve 1 is closed. Exhaust gas therefore passes the EGR passage 10 and a by-pass passage 12 and is exhausted to an exhaust pipe 9, bypassing a turbosupercharger 5. When exhaust pressure (turbine exhaust presser) detected by a pressure sensor 25 exceeds the set pressure, the auxiliary valve 13 is opened to regulate exhaust pressure.

Title: Packing agent for fast liquid chromatography
Inventor: WATABE KATSUNORI
IPC: C07C227/40
Filed: 1989-09-13
Abstract: PURPOSE:To achieve efficient separation of an optical anisotropic body by bonding optically active N-pivaloyl-valine chemically to aminoalkyl silica to make a specified structure. CONSTITUTION:An optically active vaniline is employed as starting material and converted once to an N-pivaloyl derivative to increase identifying capacity for an optically anisotropic body. The derivative is bonded chemically to aminoalkyl silica to make a packing agent for fast liquid chromatography of a structure given by the formula I. Aminoalkyl silica is preferably spherical. After the chemical bonding to aminoalkyl silica, the packing agent is packed into a column for HPLC to be a solid phase. As an interaction in the solid phase is different between enantiomers, L amino acid and D amino acid are eluted separately from a column to separate. This enables efficient separation of the optically anisotropic body. In the formula I, (n) represents 3-15 and C* is asymmetric carbon atom.

Abstract: PURPOSE:To enhance safety by spraying thermit fine particles with plasma arcs over the surface of concrete and melting the concrete surface. CONSTITUTION:A working gas Ga is supplied to a plasma torch 15 by reflow. Then, a high frequency power source 12 is used to break down an insulation between a cathode 151 and an anode 152, thereby forming a pilot arc. The working gas Ga, which is ionized and conductive by the pilot arc, is emitted outside by way of a nozzle 152. When the working gas reaches a dummy electrode 16, there is generated a main arc (A). Then, a switch 14 is turned off so as to keep the main arc in a stabilized state. The shape of the main arc (A) is a reversed cone type. A carrier gas Go is sprayed in a plasma arc environment, which forces the thermit fine articles (T) mixed in the carrier gas Gc to produce a thermit reaction by means of plasma arc heat of the main arc (A), thereby melting the concrete 7.
